Thanks for the reply, but it doesn't quite fit my requirements.

If I go up a notch in size, that also brings into play the Oughtred Eun
Mara... which, along with the Grey Seal, has to be one of the most
aesthetically mindblowing craft I've seen plans for. I'm a big fan of
the traditional look! Though I suspect that despite it's 18 or 19 foot
length - the Eun Mara is a solid notch up when it comes to
displacement, cost, launching hassle, etc.
